Description
Technical field：
The present invention relates to road performance technical field, more particularly to a kind of collapsible loess waterproofing performance of roads layer laying apparatus.
Background technology：
Collapsible loess is a kind of under drying regime, with higher-strength and compared with low compressibility, is met after water certain outer
Power act on or under Gravitative Loads intensity rapid drawdown a kind of Special Rock.Its soil property is more uniform, short texture, pores'growth,
In its forming process, sufficient pressure and suitable humidity tend not to be provided simultaneously with, and cause the densification of soil layer not good enough, closely
The soil layer that 2~3 meters of table, is influenceed by Atmospheric precipitation, typically the humidity with suitable densification, but now upper earthing weight very little, soil layer
It cannot get sufficient densification, just form the collapsible loess of low humidity, high porosity, compressibility is relatively low under natural moisture,
But when meeting water infiltration, deflection is big, occurs the fast de-stabilise deformation of subsidence velocity.It is sweet that collapsible loess is distributed widely in China
The Loess Plateaus such as respectful, Ningxia, Shaanxi and Shanxi.Collapsible loess is mainly shown as chance water to the engineering harm of highway engineering
Differential settlement afterwards, causes highway pavement Large Area Cracking, sink, so as to cause other secondary highway distresses, further adds
The settlement by soaking of acute loess foundation, causes vicious circle.So the construction quality of the collapsible loess subgrade in highway engineering is direct
Influence the construction quality and operation later stage, maintenance project phase of whole highway.
When carrying out engineering construction on collapsible loess foundation, it is necessary to consider because damp sink of foundation causes additional settlement to engineering
The harm being likely to result in, selects suitable method for processing foundation, it is to avoid or eliminate the saturated yielding of ground or caused by a small amount of saturated yielding
Harm.Built for one and complete highway, cause saturated yielding to be either pavement seepage or be side slope seepage, pavement seepage it is anti-
Control and can preferably overcome with grade by using suitable proportioning and the level of gathering materials.Get up then difficult for side slope seepage prevention
It is many, and quantities and fund input are all very big, the processing for side slope seepage is changed using integrated use when repairing the roads at present fills out, by force
Rammer, compacted, ground layer of soil or mixed lime and soil, the native method such as stake or lime soil pile, pile foundation, and use clay in embankment both sides side slope and top
Parcel processing, prevents rainwater from penetrating into.For the processing of II grades of above collapsible loess foundations as using ground layer of soil or mixed lime and soil, native stake or
Lime soil pile, pile foundation presoaking, clay parcel, have that workload is big, spend that labour is more, job site occupation of land in various degree
Greatly, long in time limit, high cost shortcoming.
In order to solve disadvantages described above, a kind of new-type embankment structure is devised, as shown in figure 1, devising tool in both sides of the road
There is a banding waterproof membrane 91 of one fixed width, waterproof membrane 91 is by the loess under the loess formation 93 of 92 times certain depths of roadbed and side slope 94
Layer 95 completely cuts off, to prevent the loess formation 95 of 94 times high-moistures of side slope from being seeped water to the lower section loess formation 93 of roadbed 92, so as to avoid rain
Ji Jishui causes side slope seepage to produce settlement by soaking.
